• Cycle time: 120 s
• Passed customer acceptance at first run

High-flexibility seat assambly solution for mixed-model automotive production.

Challenge

The customer required one line to support mixed production of two vehicle models while ensuring high automation, full traceability and fast changeovers.

Solution

Hexin delivered three assembly lines integrating assembly stations, automated inspection stations, RFID traceability, PLC-controlled process monitoring, vision-based error proofing, and force and noise testing.

Key Results

• Cycle time: 43 s/unit
• Daily output: 1,466 units
• Operators: 18

A smart engine assembly line integrating automation, AGV logistics and digital production management.

Challenge

The customer needed a flexible line for multiple engine models with mixed-model production, full-process traceability and real-time production visibility.

Solution

Hexin delivered an intelligent assembly line with automated workstations, AGV material delivery, automatic tightening and testing, dual production dashboards and MES integration for traceability and monitoring.

Key Results

• Line cycle time: ≤ 115 s/unit
• Automatic station cycle time: ≤ 90 s/unit
• Supports future model expansion

Fully automated assembly solution for precision medical components.

Challenge

The customer needed a more stable, efficient and clean production process for small, high-precision medical parts that were difficult to assemble manually.

Solution

Hexin delivered a fully automated system with integrated stations, coordinated four-axis robots, high-precision vision systems and laser welding technology for precise and clean assembly.

Key Results

•  Cycle time: 5.5 s/unit
• Fully automated feeding, assembly, welding and inspection
• Improved yield and consistency

Integrated assembly and testing line for large medical equipment.

Challenge

The customer's original production process was fragmented, space-intensive and time-consuming, while also exposing operators to radiation during testing.

Solution

Hexin developed an integrated line with a lead-shielded tunnel structure and a modular drive system with universal pallets, creating a combined assembly-and-test workflow for safer and more efficient production.

Key Results

•  Floor space reduced by 50%
• Production time reduced from 720 min to 400 min
• Efficiency improved by 44%

Automated assembly solution for household appliance components with flexible changeover capability.

Challenge

The customer's manual assembly process led to inconsistent quality, low efficiency and positioning difficulties caused by irregular incoming parts.

Solution

Hexin developed a fully automated system integrating robotic pick-and-place, automated feeding, secondary positioning, pneumatic assembly and flexible switching between product variants.

Key Results

• Cycle time: 40 s/unit
• Fully automated end-cap assembly
• Improved stability and changeover flexibility

Wheel sub-assembly line designed for international production and global quality standards.

Challenge

The customer needed a high-precision line capable of handling multiple wheel sizes with fast switching and consistent quality acorss global manufacturing sites.

Solution

Hexin delivered a sub-assembly line supporting two wheel sizes, with integrated in-line inspection and a design suitable for replication across multuple international factories.

Key Results

• Supports 18-inch and 20-inch wheel variants
• Fast product changeover
• Deployed across multiple international production sites

Fully automated end-of-line assembly and testing solution for automotive electronic components.

Challenge

The customer needed a highly automated solution for precision assembly and final testing with full traceability and stable quality performance.

Solution

Hexin delivered an integrated line combining conveyor technology, robot handling, plasma cleaning, online EOL testing and a PC-based tracebility system in one continuous workflow.

Key Results
